Dense compute platform

The Dell PowerEdge R650xs is a 1U rack server that delivers 32 total cores across two Xeon Silver 4314 processors running at 2.4 GHz with 3.4 GHz turbo. It ships with 256 GB of DDR4 2666 MHz registered ECC memory in eight 32 GB modules. Ten 960 GB SATA SSDs and a PERC H745 controller with 4 GB NV cache provide high-density storage in a single rack unit.

Build integration

Dual redundant 1400 W platinum power supplies and hot-swap drive bays keep the system running during maintenance. The OCP 3.0 dual-port 10 GbE SFP+ adapter handles high-speed networking without consuming a PCIe slot. iDRAC9 Enterprise enables remote deployment and monitoring. Ready rails and a front bezel are included for immediate rack installation.

Sustained operation

Platinum-efficiency power supplies and redundant cooling maintain stable output under continuous multi-threaded workloads. The H745 controller’s battery-backed cache protects write data during unexpected power events. ECC memory corrects single-bit errors in real time, preserving data integrity during extended compute runs. Hot-swap components allow drive or power supply replacement without downtime.

Questions about this item

What is the first bottleneck when both 16-core Xeon Silver 4314 CPUs and all ten 960 GB SATA SSDs run flat-out?

The SATA 6 Gb/s interface on each SSD caps sustained throughput well before the CPUs or the H745 controller reach their limits.

How much heat and fan noise appear after the dual 1400 W platinum PSUs and both 16-core CPUs have been loaded for hours?

Dual 1400 W platinum supplies and the 1U chassis push hot air out the rear; fan speed ramps with CPU temperature, so sustained load keeps fans at elevated RPM.

Which SFP+ modules and switch ports must I already own to use the Broadcom 57412 dual-port 10 GbE OCP 3.0 card?

The 57412 presents two SFP+ cages, so you need compatible SFP+ transceivers and 10 GbE switch ports with matching optics or DAC cables.
